Cystopteris baenitzii Dörfler; C. fragilis (Linnaeus) Bernhardi var. baenitzii (Dörfler) Ascherson & P. Graebner; C. fragilis subsp. dickieana (R. Sim) Hylander; C. fragilis var. dickieana (R. Sim) Lindberg; C. sikkimensis Ching ex Bir.

Very similar to Cystopteris fragilis, hardly distinguished from it morphologically except in spore ornamentation, i.e., perispore rugose or verrucose not echinate. It is reported that they can make sterile hybrids and form a species complex with other species. 2n = 168, 252.

Sympatric in the distribution area of Cystopteris fragilis, valleys, rock crevices on mountain slopes, on rocks in forests, damp areas in grasslands; 1400-5400(-5600) m. Gansu, Hebei, Qinghai, Shaanxi, Sichuan, ?Taiwan, Xinjiang (common), Xizang (common), Yunnan [Afghanistan, India, Nepal, Pakistan; Africa, Europe, North America].

The taxonomic status of Chinese Cystopteris dickieana is uncertain. Scottish and American C. dickieana are considered conspecific with C. fragilis, based on the variable echinate and rugose spore ornamentation in C. fragilis.
